@zbrando UK, France, Germany, Spain, Italy, and several other countries have significant military satellite capabilities.
It is not publicly known how well they compare to the US exactly, but we must use everything we have got in the best way we can.
It is known: the USA have around 200 to 260 spy satellites in orbit, all categories put together (optical, radar, infrared, elint) .
Europe, all nations combined, have less than 100 (80 to 90 are the most common numbers), France, which is the biggest European player, has about 30.
The issue is that these European satellites are not geo stationary. The USA has satellites right above Ukraine and Russia.
